Barbels two only, of small size. The osseous dorsal ray is 

 very slender, stitf, with very minute, almost imperceptii»le 

 posterior serrature. Three longitudinal series of scales be- 

 tween the lateral line and ventral Hn. Body oblong, its 

 depth being two sevenths or one fourth of the total length 

 (without caudal), the length of the head one fourth. The 

 depth of the head is less than its length without snout. The 

 diameter of the eye is one fourth of the length of the head, 

 and rather less than that of the snout, or than the width of 

 the inierorbital space (which is somewhat convex). Snout 

 rather obtuse ; mouth inferior, small. Dorsal fin of less height 

 than the body, commencing a little behind the origin of the 

 ventral, its first ray being equidistant between the end of the 

 snout and the root of the caudal, Anal small ; caudal rather 

 deej)ly forked. The pectoral does not extend to the ventral. 

 A narrow dark band runs along the middle of the side, and ter- 

 minates in a round blackish spot at the root of the caudal.

'i'jiE novelties described in this paper were contained in 

 some small collections recently received by the Britisli Museum 

 from ^ladagasear. As regards the localities, "SI. (Jrandidier 

 has kindly informed me that Anzahaniaru is the name of a 

 small village, most probably close to Mahanoro, and that it is 

 a name very common throughout ^ladagascar, meaning a loca- 

 lity where there are many country-houses. Mahanoro is a 

 short distance south of Tamatave.
